Hyundai has unveiled its Blue² concept (say “Blue Squared”) at the Seoul auto show. The concept features a hydrogen fuel-cell stack that can deliver 121 hp (90 kW), but Hyundai doesn’t get into detail about its hydrogen tank’s capacity. Fortunately, given what little hydrogen infrastructure exists, this vehicle’s powertrain is—at best—headed for a small test fleet in a city none of us lives in, so such technical details matter a little less here.

More noteworthy, though, is the Blue² concept’s styling. The Audi-esque hexagonal grille shape is borrowed from the Sonata hybrid, while the taillights recall the Genesis coupe’s (and old Infiniti G35’s). Hyundai’s Korean-market Bentley-lookalike winged badges are attached to the Blue²’s nose and tail. The car borrows from the new Saab 9-5 in its hockey-stick C-pillars, blacked-out A-pillars, and cantilever-look roof, while the handsome rims and black side graphics are pure auto-show dreaminess.

The real takeaway from the Blue² concept is that Hyundai will continue to use “Blue” branding for its eco-friendly offerings. Except when it uses the branding for infotainment, as with “Blue Link.”
